1900s:
By the turn of the twentieth century, the watch industry's first and most successful mass marketer, Robert H. Ingersoll, worked with Waterbury Clock to distribute the company's "Yankee" pocket watch, the first to cost just one dollar. Twenty years later, with nearly forty million sold, the "Yankee" became the world's largest seller and "the watch that made the dollar famous." Everyone carried the Yankee: from Mark Twain to miners, from farmers to factory workers, from office clerks to sales clerks.
